CHEMICAL ANALYSIS 17 



i decimetre = T V of a metre. 

 i centimetre = of a metre. 



i millimetre = 10 1 OU of a metre. 



i micron (p) = TTTOIT f a millimetre. 



i kilometre = 1000 metres. 



Mass. 



i gramme = the mass of i cubic centimetre of distilled 

 water at the temperature of its maximum density, 4 C. 

 or 39-2 F., i c.c. at 16 C. or 60-8 F. 0-9989 gramme. 

 i gramme equals 1 5-432 grains. 



i decigramme = T V of a gramme. 



i centigramme = T ^ of a gramme. 



i milligramme = yoV^y f a gramme. 



i kilogramme = 1000 grammes. 



Volume. 



i litre = the volume or capacity of i kilogramme of distilled 



water at 4 C. Equals 35' 196 imperial fluid ounces. 

 i decilitre = T L of a litre. 

 i centilitre = T i^ of a litre. 

 i millilitre = T7 Vo f a litre. 

 i cubic centimetre = of a litre.
